Ahh.. that awkwardness time when you get off of a cardio machine at the gym to get the wipey stuff to clean it like a good gym citizen.. only to ferget which machine you were on in the row of 13 identically crappy machines... and you pretend to be confident about the one you chose to wipe down, even though inside you are wondering if the guy on the treadmill behind you knows which machine you ACTUALLY used..
